Abstract

The present invention relates to a hydraulic vibrator used in construction machinery (such as an excavator), including a vertical support means (10) connected to hydraulic construction machinery in the upper portion, a vibration means (20) generating vibration in the lower portion, and an anti-vibration means (30) installed between the support means and the vibration means and performing buffering so that the vibration of the vibration means is prevented from being transmitted to the support means. The vibration means (20) has a geared hydraulic motor instead of an electric motor built thereinto so that the hydraulic line (hydraulic supply line and recovery line) of the hydraulic construction machinery is connected and driven without an additional drive device. No vibration is transmitted to parts other than the vibration part, and thus economic advantages and efficiency can be excellent.

Description

[0001] Hydraulic vibrator [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic vibrator for use in construction equipment (for example, a crane), and more particularly, to a hydraulic vibrator that is driven by a hydraulic motor by connecting a hydraulic line of a construction equipment Therefore, it is possible to operate at least the hydraulic pressure as compared with the piston inflow motor type by the geared hydraulic motor method, and to prevent the vibration from being transmitted to the parts other than the vibration area by the anti- will be.

Generally, a vibrator is used in a variety of industrial fields such as an airplane that hits a file and a pipe, an excavator that excavates a rock and a ground, and a concrete vibrator that stabilizes concrete when the concrete is poured .

Such a vibrator is composed of a vibrating rod that vibrates and a power portion that generates and transmits power to the vibrating rod. The vibrator is divided into a hydraulic type and an electric type according to the power of the power portion.

Since the electric vibrator needs to prepare a separate power generation device and connect it, it is very difficult to apply it according to the situation in the field. In the case of the hydraulic type vibrator, it is not necessary to prepare a separate power generation device. Particularly, in the conventional hydraulic type vibrator, since a large amount of flow rate is required mainly in the piston type, the hydraulic generator is also required to have a medium to large size, not a small size.

In addition, the conventional vibrator has a problem that it is very difficult for the operator to directly support the vibrator due to vibration of the vibrating part during operation.

Of course, there are cases where the vibration unit is mounted on a construction equipment (for example, a crane). In this case, however, vibrations of the vibration unit are transmitted to other parts of the vibration unit, There was a problem.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The hydraulic vibrator 100 of the present invention may include at least one hydraulic construction equipment (for example, a forklane) as shown in FIGS. 1 to 8, Recovery line) is connected and driven by the hydraulic pressure.

In other words, it is possible to prevent the vibration of the vibration means from being transmitted to the support means, which is provided between the support means and the vibration means, (20).

The supporting means (10) is constituted by a pipe having a hollow interior, and a hose for supplying and recovering the hydraulic pressure is built therein.

The vibration damping means 20 includes an inner coupling ring 21 screwed to the lower outer side of the tip end of the support means and an outer coupling ring 22 screwed into the upper portion of the vibration means with the first screw portion 22a, The rubber 23 is inserted and the dustproof cap 25 is threadedly engaged with the second threaded portion 22b on the outer side of the outer coupling ring.

The geared hydraulic motor 32 is installed inside the upper body 31a, 31b are provided with a shaft 36 connected to the motor shaft of the geared hydraulic motor 32 for rotational driving and supported by the upper and lower bearings 33a and 33b and a vibrator 37 eccentrically installed on the shaft. And a head cap 40 is coupled to a lower portion of the lower body 31b.

The hydraulically operated vibrator 100 of the present invention is installed in parallel with hydraulic construction equipment (for example, a fork bracket) 200 in such a way that a half of the vibration range P of each vibrator 100 overlaps with each other, It is preferable to arrange such that a space that does not cause an operation does not occur.

Reference numerals 33 and 33 'denote bearing housings.

Hereinafter, the operation and operation of the present invention will be described.

The hydraulic vibrator 100 of the present invention is installed in parallel with at least one hydraulic construction equipment (for example, a crane) vertically as shown in FIG.

And the hydraulic line (hydraulic supply line and recovery line) of the hydraulic construction equipment is connected to be driven without a separate drive device.

That is, the hydraulic line of the hydraulic construction equipment is pulled and connected to supply the hydraulic pressure to the geared hydraulic motor 32 in the vibrator 100 to drive the geared hydraulic motor 32.

In the hydraulic vibrator 100 of the present invention, the upper support means 10 and the lower vibration means 30 are combined and mounted on the hydraulic construction equipment (for example, a fork bracket) by the support means.

In this mounted state, the hydraulic pressure supplied to the internal geared hydraulic motor 32 of the vibration means 30, that is, a small amount of flow by the conventional piston hydraulic motor, is applied to the upper and lower bearings 33a and 33b And the vibration is generated by the vibrator 37 provided on the shaft portion to transmit vibration to the head cap 40 to perform various operations.

That is, a vibration preventing means 20 for absorbing vibration is provided between the vibration means 30 and the supporting means 10 to prevent the vibration of the vibration means 30 from being transmitted to the upper supporting means 10 other than the vibration portion It will be done.

This is achieved by providing an inner coupling ring 21 which is threaded on the lower outside of the tip of the support means 10 and an outer coupling ring 22 threaded on the inside of the top of the vibrating means 30 by a first threaded portion 22a, The vibration absorbing rubber 23 is inserted and absorbed to prevent the vibration of the vibration means 30 from being transmitted to the upper supporting means 10 in addition to the vibration portion.

In this way, the vibration absorbing rubber is absorbed by the vibration-proof rubber 23. The vibration-proof rubber can be easily detached and replaced by unscrewing the vibration-proof cap 25 and releasing the screwed state of the supporting means 10. [ will be.

Therefore, the present invention is driven by a hydraulic motor type by connecting a hydraulic line of a construction equipment (for example, a crane), not an electric motor, mounted on a construction equipment (for example, a forklane) The geared hydraulic motor system can operate at a minimum hydraulic pressure as compared with the piston inlet motor system, and vibration is not transmitted to parts other than the vibration area by the vibration-proof rubber.
